Poland's state development bank, Bank Gospodarstwa Krajowego (BGK), has invested €25 million in SWEN Capital Partners' SWIFT 3 infrastructure fund, targeting biogas and biomethane development across Europe and OECD countries.
The SWEN Impact Fund for Transition 3 (SWIFT 3) is the third vehicle under SWEN's investment strategy, which launched in 2019. It focuses on decarbonising sectors where emissions are difficult to reduce, including the natural gas industry. BGK's contribution is expected to support projects capable of producing nearly 20 million m³ of biomethane annually.
Other investors in the fund include the European Investment Fund (EIF) and COFIDES, Spain's leading development finance institution.
Poland has significant untapped potential in the biomethane sector — among the highest in Europe — yet had only around 400 biogas plants and a single biomethane plant in operation as of 2025. BGK framed the investment as a response to that gap, with Jarosław Dąbrowski, a member of the bank's management board, noting that the country's low-carbon energy opportunity had so far gone largely unrealised.
Biomethane features in Poland's National Energy and Climate Plan (NECP) as a renewable substitute for natural gas, contributing to energy source diversification and system stability. The EU's REPowerEU initiative has set a target of 35 billion m³ of annual biomethane production, and BGK has positioned Poland as a potential key contributor to that goal.
The SWIFT 3 commitment sits within BGK's 2025–2030 strategy to scale up capital investments. The bank has previously invested €25 million in the Eiffel Transition Infrastructure Fund and €20 million in Future Energy Ventures.
